Everybody has is looking for an edge -- some magical metric that makes their fantasy football rankings, projections and sleeper lists infallible. That metric doesn't exist, but if you want something that's often overlooked and should be included on your 2019 draft cheat sheet, look no further that consistency ratings.

It’s easy to chalk up every shortcoming of fantasy team to bad luck. Sure, injuries are mostly that, as are weird weather factors or coaching decisions. But some players are simply more consistent than others, and you can take advantage of that.

The tools section of BigGuyFantasySports.com has a Clutch Report to help with this. Each player type has a point total that equals a Clutch Game for a week. For example, in a 12-team PPR format, a wide receiver needs to earn over 10 fantasy points in a given week to earn a "Clutch Game". From there, we figure out his "Clutch Rating" (CR). The most consistent players will have a CR of 70 percent or better. The best of the fantasy world will normally be higher than 80 percent.

Wide receiver features plenty of consistent pass-catchers, but fantasy owners are likely more worried about the boom-or-bust options. Picking the wrong one could make or break your season.

A ranking of WR1A means I expect that player to earn an 80 percent or higher Clutch Rate in 2019. I currently only have four receivers ranked at that level. Two of the four (DeAndre Hopkins and Davante Adams) had 100-percent CRs last year. The other two (Julio Jones and Odell Beckham, Jr.) certainly have the potential to finish over 80 percent in 2019, as well. The remaining eight wide receivers are all ranked as WR1Bs, which means I project them to finish above 70 percent. Obviously, higher-ranked guys like JuJu Smith-Schuster and Michael Thomas are expected to be well over 70 percent, but 80 percent might be the ceiling. The lower-ranked wide receivers certainly could exceed a 70-percent Clutch Rating, but they are less likely. One receiver that may surprise you in this top 10 is Julian Edelman. However, his 92-percent consistency rating in 2018 shows his tremendous value in PPR leagues. He’s a great value at his current ADP of WR15.

The WR2A players have proven to be consistent over time and should remain between 65 and 70 percent consistency this season. The WR2B tier is a collection of wide receivers that have the potential to earn more than a 60-percent ranking. Robert Woods ranks as a WR14 in PPR due to his quiet 88-percent consistency last year. This tied him for eighth in the consistency rankings. He is also undervalued with his current ADP of WR19.

The WR3 group consists of receivers that I expect to earn between a 50 and 60 percent Clutch Rating. Some are young receivers moving up from last year, like Tyler Boyd, D.J. Moore and Dante Pettis. Others are veterans falling from their higher-tier status of fantasy seasons past, like Marvin Jones and Allen Robinson.

I realize that Jackson isn’t one of my favorite receivers when it comes to consistency, but he had been playing in a very crowded Tampa Bay receiving corps with Mike Evans, Chris Godwin, Adam Humphries and O.J. Howard. Now he goes back to Philadelphia to mostly compete with Alshon Jeffery and Zach Ertz. Jackson had a 58-percent Clutch Rate (29th) in 2018. His current ADP is 47th among wideouts, so grabbing him as a WR3 or WR4 would be excellent value if he just matches his 2018 consistency numbers.

Overvalued: Amari Cooper, Cowboys

Talk about a tale of two halves for Cooper in 2018. He was abysmal for the first eight weeks, but after being traded to Dallas, Cooper caught fire for six weeks and earned five Clutch Games. His ADP is still a bit high though at WR12. It’s not so much a question of Cooper’s production but of his value, and there are much more consistent players, such as Julian Edelman, who you can draft two rounds later.
